Quoted from swinks:reseating the ribbon cables at the board and dmd did not change anything, nor the MPU
I checked out the U24 chip and it appears to have a socket there already and a different chip compared to the rest of the board's chips.
Any ideas what I have?
Do I just hunt down a 6264 Ram Chip?
Does the Chip need any programming or is it a simply remove this chip / board and insert the new chip?
ps - ignore the led night blur

just because it is on the pin out adapter board does not make it a NVRAM device. whoever installed it may have only had surface mount 6264. i would try a new ribbon cable between mpu and display board before trying to replace the chip if you have another WPC game to borrow ribbon cable from. any 6264 chip will work here. it does not need programmed.
